 ## Prerequisites
 
-| Requirement | Notes |
-|---|---|
-| **tmux** | Must have at least one session running (`tmux new -s main`) |
-| **ttyd** | WebSocket bridge — `brew install ttyd` (macOS) / `apt install ttyd` (Debian/Ubuntu) |
-| **Python 3.11+** | Required by the muxplex server |
+- **Python 3.11+** — installed via `uv` or system Python
+- **tmux** — terminal multiplexer
+  - macOS: `brew install tmux`
+  - Ubuntu/WSL: `sudo apt install tmux`
+- **ttyd** — terminal sharing over HTTP (required for interactive terminal access)
+  - macOS: `brew install ttyd`
+  - Ubuntu/WSL: `sudo apt install ttyd` or `sudo snap install ttyd`
+  - Other: https://github.com/tsl0922/ttyd#installation
+
+> **Tip:** muxplex checks for `tmux` and `ttyd` at startup and prints install instructions if either is missing.
